Hello,
I'm having string inconsistencies for the size of share.
In Resilio Sync; It advertises as 47Gb - 30.967 files.
If I select all the files in the folder, right click and check properties it says 12.9Gb.
If I right click the directory it says almost 200GB and 225.045 files.
Why is this happening? Why all show different sizes? You can see screenshots attached.
Note: All selected files have .sync folder selected as well.

That's probably where the problem is.
Type the following
wget https://download-cdn.resilio.com/2.6.3/Debian/resilio-sync_2.6.3-1_armhf.deb
sudo dpkg -i resilio-sync_2.6.3-1_armhf.deb
This will override the previous installation. Then check from the web interface that Raspberry Pi is also running 2.6.3
